To further demonstrate the effectiveness of the proposed Invo-ResNet, the comparison of the confusion matrices at 10dB of ResNet [1]}, MSNet [2]} with those of our proposed scheme are shown in Fig. REF . It is seen that the proposed Invo-ResNet has less confusion compared to other traditional models. Specifically, only AM-DSB-WC receives the worst performance in our proposed scheme. On the contrary, two modulation formats perform worse in ResNet and MSNet, which are AM-DSB-SC and 64QAM, and AM-DSB-SC and AM-SSB-WC as shown in Fig. REF  and Fig. REF , respectively.
